I have a problem that occasionally I get an "Error: failed to connect to NBD server"

02:38

<alkisg>

Occasionally? Not always? Check if you have another dhcp server on your thin client subnet

02:38

<biomorph_>

Mmm..... Ah - that's an interesting one.....

02:40

Yes I think that could explain it..... Doh - why didn't I think of that.

02:42

OK - the reason I am trying to do this is that I get crashes on some machines, but not others. I am convinced this is caused by https://wiki.ubuntu.com/X/Bugs/Lucidi8xxFreezes

02:42

Anybody else seeing crashes/freezes when using Intel graphics chips.

02:44

<alkisg>

Yes, I had to use a ppa kernel for my wife's laptop which has intel 855

Hey, new fixes there... we need to send feedback to them :)

02:45

<biomorph_>

alkisg: is there an upstream bug report I could follow to see when it gets fixed?

02:46

<alkisg>

biomorph_: I don't know, but we're supposed to test those proposed fixes to get them upstream

02:46

Otherwise they'll just drop them

02:46

(it's been done before...)

02:46

<biomorph_>

alkisg: And what kernel do you use?

02:47

I've had some success using kms for the intel chip.

02:47

<alkisg>

Can't check now, I can tell you in 30' if you're still here

02:47

<biomorph_>

I will be, thanks.

02:47

<alkisg>

I tried nomodeset etc, only limited success. With the newer kernel everything was solved, it's been running for months without problems

biomorph_: I've been using this kernel: https://launchpad.net/~brian-rogers/+archive/experimental But as I read on the bug reports (e.g. https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/511001) that's not recommented, the best is to test the drivers from the wiki page

OK - I'm going to try enabling KMS - that works best for me at home.

03:03

So my question is is there any point in enabling it in /etc/modprobe.d/i915-kms.conf or should I just do it in /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default

03:03

Problem with second option is that that gets overwritten every time I run ltsp-update-image

03:07

<alkisg>

$ grep BOOTPROMPT_OPTIONS /etc/ltsp/ltsp-update-image.conf

03:07

BOOTPROMPT_OPTIONS="quiet splash nbd_proxy=false"

03:08

You can put it there ^^^

03:09

<biomorph_>

alkisg: Thanks I was looking for that. Didn't want to change the actual script, but did think about it.

03:09

<alkisg>

But really, reporting back is the only way to avoid the problem in the future.

OK - I'm back. One little annoyance I have is that if I log on to the client (I have enabled a root password) it is defaulting to US keyboard. Anybody know quickly how I change that to a UK keyboard?

06:06

<alkisg>

biomorph_: about the intel 855 card, I tried the new workarounds with mine and the best one was still to use the new patched kernel - otherwise I it crashed with XV

!lts.conf

06:06

<ltspbot>

alkisg: "lts.conf" :: http://manpages.ubuntu.com/lts.conf

06:06

<alkisg>

For the keyboard, see the man page

06:07

(otherwise run dpkg-reconfigure console-setup on the chroot, or specify a locale when running ltsp-build-client)

06:15

<biomorph_>

alkisg: Thanks for both bits of info. Intel drivers are really getting me annoyed. KMS certainly fixes one problem. I'm going to have to leave the customer to test whether it works for a full day.

06:15

<alkisg>

What have you tried? Disabling KMS?

06:17

<biomorph_>

No - I've tried enabling KMS. With KMS disabled if I switch between VT7 and VT1 before logging on to the LDM screen I was get a crash when I go back to the LDM screen.

06:17

KMS enabled I never get that crash.

sorry on first post s/was/always/

<alkisg>

Maybe you have a diffent model than mine then, I have KMS enabled by default but X crashes before ldm.

It is so annoying we have considered buying cheap graphics cards on EBay

06:22

These machines worked with no problems until update to Lucid.....

06:23

<alkisg>

Yeah that GEM change :-/

06:23

I've 855, different symptoms, and again wouldn't work on lucid without that patched kernel

hi (base system ubuntu 10.04), what happened to the option in the alternate installer (install LTSP) as per https://help.ubuntu.com/community/UbuntuLTSP/LTSPQuickInstall? should LTSP be installed in a different way now?

Is there a trick to getting EdUbuntu 10.04 ltsp to work properly? I am getting an NBD error when I try to boot my thin clients. Any help would be appreciated.

13:43

<johnny>

be more specific, and stick around for an answer

13:52

<rpm_>

Here is the error Error: Failed to connect to NBD server, and then it says something about busybox

13:56

<johnny>

and on your edubuntu server, your /etc/inetd.conf references nbd ?

13:56

and not just nbd-swap

13:56

if so, how many dhcp servers do you have?

14:01

<rpm_>

Thanks Johnny, I am asking this question after the fact, I was in a rush on Friday to get a server up and running and kept getting that error. I ended up having to revert to 9.10 but I want to go to 10.04, as a result I don't have it running any more. I will be trying again in the near future so I thought I'd ask before hand what could cause that. I found the same error on alot of different forums but no real answers, is editing the ine

14:05

<johnny>

no

14:05

Hey all, Anyone know of good place to look for ltsp cluster install info, I was noticing it had a lucid package but was on the website and not seeing much as far as install is concerned?

14:06

hey grantk, the best writeup for cluster I have found is on the ltsp cluter homepage, unfortunately it isn't using 10.04 so you

14:10

you'll have to apply what is there to 10.04 as see if it works

14:10

<Appiah>

I used it to get hang on how ltsp-cluster works and installed on 10.04

14:10

worked

14:10

<grantk>

cool, sounds good!

14:10

good luck

14:11

I should do it again and document it ...

I will be documenting for work here so if It works out well I'll send what I did to the mailing list

rpm_: for nbd I've seen 3 possible problems: (1) wrong /etc/inetd.conf configuration, (2) wrong dhcp setup (either dhcpd.conf or multiple servers), and (3) nbd-proxy problems. The first 2 are the most common, and are really easy to fix. For (3) there's a bug report in launchpad, but it's not very common.

I know my dhcp server is working right so I think it may be the first, what do I need to change in the inetd.conf file?

14:24

<johnny>

paste the one that doesn't work

14:24

once you reinstall

14:24

<alkisg>

Are you absolutely sure there's no other dhcp server around?

14:26

<rpm_>

absolutely sure. I don't have the 10.04 server up anymore because I had to get something working for today so I put 9.10 on it instead and it is working fine. I am planning on putting 10.04 on in the very near future so I am asking in advance in case I run into the problem again.

I have an ubuntu 10.04 ltsp server that I installed with the alternate cd. Having some networking issues, and was wondering if I can make this work as my default dhcp server, which also needs to serve up a separate image

15:30

<grantk>

litercola, yes you can

15:30

I have mine serving up some images for a phone system

15:30

<litercola>

thanks, that's pretty cool

15:31

what distro are you using?

15:31

<grantk>

ubuntu 10.04

15:31

<litercola>

I have had alot of trouble with dhcp3 server not wanting to start up on boot

15:32

<grantk>

I have actually had that happen recently and then it just stopped, I did not find any complaints in dmesg and logs

15:33

<litercola>

in syslog mine tells me that dhcp is not listening on any interface

15:34

but when i restart it says stopping: faild, starting ok

15:34

<grantk>

I have my clients all defined in my dhcpd.conf for the phones so that makes it easier, you should be able to use the option vendor-class-identifier too, but I never went to the trouble since I was using static ip's anyway

15:34

<litercola>

will the man pages help in configuring certain mac adress to look to another server for a different image?

15:35

<grantk>

yeah they did a bit, I still looked elsewhere

15:35

<litercola>

btw, did you install from alternate, or do a server install and drop ltsp on top?

15:36

<grantk>

server first

15:36

<litercola>

very cool, thank you

15:37

<grantk>

np

15:38

<litercola>

one more, did you install x on your server?

15:38

I guess im wondering if it will build my client images with a desktop by default, or based on what the server has?

15:39

<grantk>

I think it goes with what is on the server, and yes I did because I used a xenserver image that already had it installed but I have disabled X.

15:40

<litercola>

thank you, you have been very helpful. I figured I should have done a server install to begin with, with the way things have been going, I think that I will regret not starting over with that now.

15:40

<grantk>

np, I am not sure how the alternate goes, just was not an option because I did not want to build the xen kernel as well!

15:41

thanks again, later
